My invention relates to a method and device for uniting package and balebands and the like. In order that the overlapping ends of metal bandsfor tying light packages and the band-iron binding for heavy cases andbales may be firmly united, it has been customary heretofore to employdevices in the form of pincers or small hand machines, the actualoperative members of which, upon being moved forwards against the bandand transverse to the longitudinal direction of the band, madeembossings in same, after or without previous cutting of incisionstherein, the two overlapping layers of band being immovably andinseparably held together by these embossings in a longitudinaldirection and also-with or without the assistance of a metal sleeveplaced over the jointtransversely to the plane of the band.

Besides effecting the union by means of connected tongues formed byparallel incisions made transversely or longitudinally to the directionof the band, it has also been proposed to bring about the fastening bybending together the overlapping band ends transverse to theirlongitudinal direction to form a tube, so that they may no longerseparate in the transverse direction, and after or simultaneous with theformation of the double tubular member, impressions were made in thewalls thereof, to prevent also a longitudinal displacement of the twowalls of the tube.

All these well known devices require very considerable forces to make astrong and resistant union, because the deformations necessary to twistthe overlapping band portions must be brought about by a single effortdirected transverse to the band, or at the best by two of such pressingoperations occurring successively. Furthermore, .due to the powerfulgrip of the tools effecting the union, the strength of the band materialat the joint is more or less considerably weakened.

According to the'present invention, the defer mations necessary to bringabout the union between the two overlapping band ends, are produced notas heretofore, but successively over the entire length of the joint atonce,by arranging that the two tools bringing about the change of shapeand which are combined into a common rolling motion, roll along thebands for the length of the desired union. The uniting of the two bandstransverse to their length is preferably brought about by folding orcreasing them together in their longitudinal direction. The fixingagainst displacement of the joint in the longitudinal dimotion ispreferably brought about by alternately opposite impressions, which givethe folded union a form corrugated in a series of short bends.

In applying the process there is the advantage that the resistiveeflfort due to the deformations necesssary to make the union aredistributed substantially uniformly over a rather long distance, becausethey are produced successively and by a rolling rotation of the pair oftool members. The maximum compressive forces essential to bring aboutthese changes of shape and which determine the transmission ratio of therequisite lever mechanisms and the strength of the tool members, areconsiderably less than in the case of tools which bring aboutcorresponding deforma-- tions by operative movements actingperpendicular to each other. Moreover the tools required are relativelysimple in form' as they may be developed from the body of a pair ofmutually engaging toothed pinions by making suitable excisionstherefrom.

The invention will be understood more clearly by reference to theaccompanying drawings which show preferred embodiments of the means forcarrying out same, as well as other explana tory details.

The tools for carrying out the process are preferably in the form of twomeshing pinions or small gear wheels 1 and 2, which have their spindles3, 4 mounted in a slide or carriage plate 110 5, the gear wheels beinglocated to one side of the carriage plate and gear wheel 1 being securedto and rotatable with its spindle 3. The

wheels 1 and 2 each have an annular recess 6, passing through all teethand running round the greater portion of the periphery of the wheel andnear the outer face of same; At mutually opposite places there are alsoexcisions or insertion openings 7 which extend beyond the planes oftherecesses 6 and into which the ends of the metal bands 8, 9 to bejoined (possibly having turned-over edges 10) may be introduced untilthey reach the plane of the recesses 6.

As will easily be seen, by a suitable contrary rotation of the twopinions 3, 4 the two insertion openings will move away from each otherso that the metal bands will first be engaged by the .bottoms of therecesses 6 and then pressed together in a transverse direction, sothat acom mon'longitudinal folding of the band ends results. In order toensure the same direction of bending, that is the folding of the end ofthe inner band into the outer one, the metal band, previously preparedfor the purpose is given a slight preparatory bend. When bands withturned-over edges are used, the longitudinal folding generally takesplace in the correct manner without any preparatory bending. 4

During the further progress of the rotary motion, the bottoms of therecesses 6, walled at their ends by full depth portions of the pinionteeth, force themselves with rolling pressure laterally from the sideinto the band material now of four-fold thickness and by forcing sameinto the spaces between the teeth of the coacting wheel, which arepreferably. somewhat widened, make lateral impressions or shortcorrugations 11 therein. At the same time the outer edges of the outsideband end are so forced into the inside band end, that in the union withthe transverse fold,-a separating movement towards the open side of thelongitudinal fold is also impossible. Due to this and to the alternatelateral impressions, a very resistant union of two ends of the metalband is broughtabout. After completing one whole revolution of the twopinions, the two insertion openings 7 of the two pinions are againopposite each other, so that the finished joint is released.

A device which is suitable for making hoop fastenings by using the abovedescribed method, is shown in Figs. 5-11. On the flat base plate 12 ofthe 'mechanism a guide spindle 14 is mountedin two bearings 13 parallelto the surface of the base plate. The carriage plate 5 carrying thepinion tools 1, 2 is slidably and pivotally mounted on this guidespindle14. At the side of the carriage plate opposite to that on which the twopinions 1 and 2 are located, a large gear wheel 15 is secured on thespindle 3' of the pinion 1 which spindle is rotatably mounted in thecarriage plate. Engagingwith gear Wheel 15, is a small toothed wheel 16,which is secured to a crank-handle spindle mounted perpendicularly inthe carriage plate. there is secured a crank-handle 18, by means ofwhich the toothed Wheel 15 and the pinion 1 may be rotated. The secondpinion 2 meshing with the pinion 1 is borne freely rotatable by a block20 and on the carriage is a lug 19 which,

with the carriage in the position shown in Fig. 6, lies clear of theblock 20 so that the carriage At the top of the. spindle.

can swing on the spindle 14. When, however,

of a spring 21 on the spindle 14 as in Fig. 7, the lug 19 engages on topof the block 20 so that the carriage cannot swing on its spindle. Thusduring the crimping operation the carriage is held from swingingmovement.

At a certain distance from the carriage plate when in its rest positionat the right-hand side, a fiat rocker 22 is arranged pivotally about avertical screw 23, upon the base plate. It is held in its rest positionby a spring 25, secured to the base plate by means of a screw 24, sothat it is urged against a stop pin 26 on the base. Arranged on theupper side of the rocker 22 is the flat body 27 of the bottom blade ofthe shearing device and this body has its rear end secured to saidrocker by the screw 23. The blade 27 is fiat to permit it to be insertedbetween the band ends 8 and 9 without too greatly separating these ends.Approximately in the middle of its length this bottom blade is traversed.by a pin 28 pro- 1 truding from the rocker, its head serving as a edgeof this top blade extends forwardly from its pivot and its opposingcutting edge is formed by the top edge of the narrow, adjacent face ofthe bottom blade portion situated in front of the protrusion 30. The topblade carries an upwardly directed angle arm 32, which is engaged by aspiral spring 33, Whose rear end engages with a spring support 34arranged at the rear of the bottom blade member 27. A stop pin 30provided on the protrusion 30 determines the rest position in which thetop blade is held by the spring 33.

At a certain distance from the left-handsupport 13 for the guide spindle14, a device is mounted on the base plate 12 whose duty it is, before orduring the making of the union, to hold and if necessary to tighten theends of the metal band forming the binding. This device is borne by abearing lug 35 mounted on the base plate 12 and provided with a holerunning horizontally, but perpendicular to the guide spindle 14.Rotatabl'y arranged in this hole is a bush 36 through which runs ahorizontal pin 37, which is eccentric to the axis of its outerface. Thebushing 36 is provided at its forward end with an integral operatinglever 46.

the lever a ratchet wheel 39 is fixed and is engaged by a pawl 40 whichis arranged rotatably about the pin 41 at the back face of the ratchetlever and is kept in engagement by a spring 42.

At the front end of the pin 37, a tightening roller 43 is fixed and is'provided at its surface with grooves or serrations running axially.

When the device is to be used, the end 9 of the binding hoop, aftermounting the fastening de-.

vice on the package and swinging up the carriage plate 5 by means of thecrank handle 18, is placed in the upright position, between the shearingrocker 22 and the front part of the bottom blade 27, and in such aposition that the free end 9 of this hoop end, at a certain distancefromthe right-hand rest position of the two pinions 1, 2 over the base plate12, is carried by a supporting block 45 at a certain height above thisbase plate. Further the band is passed between the tension roller 43 andthe lug 44 of the clamping device. After passing round the package, theend 8 of the band is led over the other end 9 of this band, between thebottom blade 27 and the top blade 31 of the shearing mechanism and then,resting directly on the bottom band portion 9, under the tension roller'43. In order to permit the insertion of the hoop in the clamping device,it is first necessary, by throwing the clamping lever 46 to the left, soto set the eccentric bush 36 associated with it, that the pin 37 withthe tension roller 43 is sufficiently withdrawn from the supporting faceof the lug 44. By suitably turning this eccentric bush, which forinstance can be brought about by turning 'the clamping lever 46 to theright by hand, the peripheral surface of the tension roller 43 isdepressed onto the top band end 8 and thereby clamped together with thebottom band end against the bottom lug 44. When the ratchet lever 38 isthrown to the right, then due to the action of the pawl 40 on theratchet wheel 39,

the tension roller 43 is rotated in step in clockwise direction takingthe top band end 8 to the left with its toothed periphery, whilst thebottom band-end is fixed in its position by the teeth of the stationarylug 44. Due to the movement of the ratchet lever 38, the band bindingmay be tightened round the package to the desired extent.

In order to facilitate the operation of the clamping device, the ratchetlever 38 is provided with a forwardly directed driving pin 4'7, which"is so arranged that, near the front limit of travel of the ratchetlever with the tension roller raised, it strikes against a projection 48provided on the flat boss of the clamping lever. During the continuanceof this movement it carries the driving pin along until, due to theabove-mentioned rotation of the eccentric bush 36, it forces thetightening roller 43 downwards into the clamping position permitting theabove described tightening operation. At its base at 49, the clampinglever 46 has a bent portion which is so shaped that the end of the pin47 during the return movement, can freely pass on this clamping lever,in order to prevent the unintentional release of the clamping deviceduring the execution of the tightening movement by means of the tensionlever.

When, after the tightening of the hoop binding by means of the crankhandle 38, the carriage plate 5 is swung down forwards, the two pinions1, 2 pass with their oppositely facing peripheral excisions or insertionopenings 7 beyond the two band portions 8 and 9 supported by the blockand rest with their front ends on the surface of the base plate, so thatthe hoop portions 8 and 9 find themselves in the middle of the recesses6 of these pinion tools.

Now if the crank handle 18 is rotated in clockwise direction, thetoothed wheel 15 and the pnion 1 are rotated in opposite directionswhilst the pinion 2 is taken round in the same direction of rotation asthe crank. Thus as previously described, the two bands are first'foldedtogether in the longitudinal direction and then intimately joinedtogether by mutually alternating impressions as will be seen from Figs.12 and 13. Due to the rolling movement of the pinion tools 1, 2 on theband portions secured by the binding, the

' tool carriage is pushed to the left against the tenfromFigs. 12 and13.

sion of the spring 21 on the guide spindle 14. The lug 19 then slidesover the surface of the guide block 20 and prevents the carriage plate 5with the pinion tools from being swung out of their working positionwhen in this intermediate position. At the bottom of the toothed wheel15 at a suitable place, there is fixed a pin or nib 50 which,

after an appropriate forward movement of thecarriage 5 and acorresponding rotation of the toothed wheel 15, presses against theangle arm 32 of the top blade 31 and so moves this blade downwards sothat it just passes over the cutting edge .of the bottom blade 27 andthus cuts off the protruding end of the top band portion 8.

Shortly after this operation, during the further advance of the carriageplate 5, a striking arm 52 secured to the latter hits against theshearing rocker, so that after the pin or nib has passed by the top endof the cranked lever 32, the rocker is swung out to the left about itspivot 23 against the action of the spring 25. The arrangement is somade, that the two operative pinions 1, 2 before completing a wholerevolution from the starting position, can pass somewhat beyond theshearing position by virtue of this deflection of the shearing device,so that the folding action of the two pinions continues somewhat beyondthe sheared edge 53 of the top metal band '8, as will be seen Thisprevents the protruding of the top band beyond the joint and eliminatesthe danger of injury being done to the hand. In the case of the bottomband end 54, this danger is eliminated by it being covered by the upperband 8 of the joint.

situated above it. When a Whole revolution of the two pinions has beencompleted, the two gaps 7 of same pass into the starting mutuallyopposite position. Thus the pinions lose their hold on the corrugatedfiat portion of the joint, so thatthe carriage plate together with theparts thereon is pushed back again by the spring 21into the startingposition at the right hand side.

In order to fix the parts in the proper place in this starting positionand also to secure the crank handle 18 in a forward position so that itcan serve as a handle for pivoting the carriage plate, there is provideda suitable catch mechanism which, in this position of the crank offers acertain resistance forwards and backwards. For

this purpose a catch 55 is arranged longitudinally forwards, the sharpend of this nib snaps into the notch of the catch 55 and secures therotatable parts in this position with a certain resistance. By swingingover the carriage plate 5 by means of the hand lever 18, the band jointcan be released, so that after the releasing of the band clamp-broughtabout by throwing over the clamping lever 46the forward parts lyingunder the binding band are withdrawn and the device can be freed fromthe finished joint. In order to facilitate the manipulating of thedevice it isprovided with an upwardly directed, preferably sphericalhandle at the end of a rear projection on the base plate.

The embodiment of the device shown in Figs. 14 and 15 difiers in itsoperations from that of the lut device shown in Figs. 5-11 chiefly bythe fact that the longitudinal movement of the two pinion tools at thejoint of the band ends, instead of taking place through the rollingmotion of these tools on the band parts, is brought about by positivemeans. For this purpose an idler gear wheel 59 is arranged on theunderside of the carriage plate behind the pinion l on the axis of thegear wheel 15, and rotates about a pin 58 secured to this carriage plate5. This idler wheel 59 meshes on one side with the pinion 1 and on theother side with a rack 60, which is secured to the base plate.

As will easily be seen, due to the action of this intermediate wheel onthe rack during the rota,- tion of the crank handle 18, the carriageplate 5, and hence the pinion tools. borne'by it, is given a forwardmovement to the left, so that the rolling action of the working face ofthe pinions on the band sections in .between, is brought aboutpositively. The crank handle 18 is, as has already been fully described,arranged to drive the shaft 3'through the gears 16 and 15.
